BTC RPC Explorer

Simple, database-free Bitcoin blockchain explorer, via RPC. Built with Node.js, express, bootstrap-v4.

This tool is intended to be a simple, self-hosted explorer for the Bitcoin blockchain, driven by RPC calls to your own bitcoind node. This tool is easy to run but currently lacks features compared to database-backed explorers.

I built this tool because I wanted to use it myself. Whatever reasons one might have for running a full node (trustlessness, technical curiosity, supporting the network, etc) it's helpful to appreciate the "fullness" of your node. With this explorer, you can not only explore the blockchain (in the traditional sense of the term "explorer"), but also explore the functional capabilities of your own node.

Live demos are available at:

Features

  • List of recent blocks
  • Browse blocks by height, in ascending or descending order
  • View block details
  • View transaction details, with navigation "backward" via spent transaction outputs
  • View raw JSON output used to generate most pages
  • Search to directly navigate to transactions or blocks
  • Mempool summary, showing unconfirmed transaction counts by fee level
  • RPC Browser to explore all of the RPC commands available from your node
  • RPC Terminal to send commands to your node
  • Currently supports BTC, LTC (support for any Bitcoin-RPC-protocol-compliant coin can be added easily)

Getting started

The below instructions are geared toward BTC, but can be adapted easily to other coins.

Prerequisites

  1. Install and run a full, archiving node - instructions. Ensure that your node has full transaction indexing enabled (txindex=1) and the RPC server enabled (server=1).
  2. Synchronize your node with the Bitcoin network.

Instructions

  1. Clone this repo
  2. npm install to install all required dependencies
  3. Edit the "rpc" settings in env.js to target your node
  4. Optional: Change the "coin" value in env.js. Currently supported values are "BTC" and "LTC".
  5. npm start to start the local server
  6. Visit http://127.0.0.1:3002/
